Peru is located in one of the highest seismicity areas. In consequence, earthquakes of great magnitude have ocurred, such as those that happened in Yungay - Ancash in 1970 and Pisco - Ica in 2007. Unfortunately, these events produce phenomena of liquefaction in sandy soils of low compactness with high water table levels. In this instance, the soils behave like a viscous fluid, losing resistance. The phenomenon of liquefaction was recorded in the district of Tambo de Mora during the 2007 earthquake, where houses were severely damaged. No further studies have been conducted to determine the liquefaction potential in this District since 2008. This sufficiency work proposes two methodologies to determine the liquefaction potential using data from the MASW-MAM geophysical tests implemented by SENCICO in 2021 and Microtremors carried out by CISMID. For this reason, it was necessary to analyze the shear wave velocities of the one-dimensional profile of the MASW - MAM matrix and the spectral ratio (H/V) presented by Nakamura. In addition, data was collected such as: Water table level, soil density, fine content, seismic magnitude (7.9 Mw) and the horizontal acceleration at surface level (0.49 g). To obtain the safety factor (Fs) and the liquefaction potential index (IPL), the methodology of Kayen et al (2013) was used, and the vulnerability index (Kg) of Nakamura. Both methodologies showed critical areas whose strata can suffer liquefaction in different degrees.
